Opening .IFO with PowerDVD Ultra

[kestrel07]

Im trying PowerDVD v7.3 Ultra.
I experience that opening VIDEO_TS.IFO from hard disk DVD folder seems no more possible. The default action of .ifo file is correctly "Play with PowerDVD", but the result is PowerDVD telling "No disc in drive D:" where D: is dvd reader letter.
Im using XP sp2. I tried in a clean installation of XP (virtual machine) with same result.
I reinstalled 7.0 version, and IFO file returned correctly associated and working.
I compared the .IFO file association between version, and it is identical both in 7.0 and in 7.3.
Any suggestion?
Thanks.

powerdvd changed the way they open dvds on a hard drive again. point it to the folder containing the video_ts folder and it will play.
